Want to know how to get the most out of your experience, whether on a connected or wireless device? Here's an MLB.com guide to the season for today's digital fan:
MLB.TV. Signups are under way for MLB.TV Premium ($124.99 yearly or $24.99 monthly) and basic MLB.TV ($109.99 or $19.99), and the MLB.TV Free Game of the Day is good if you want to take a test spin. This marks the 10th season for watching live out-of-market baseball, and the first sports league to stream live video of its full schedule now leads the way in most devices supported, even adding Xbox 360 and, most recently, Western Digital.
MLB.com At Bat 12. You can use that MLB.TV Premium subscription to watch live games anywhere. Just updated for regular-season mode, the award-winning app includes upgraded Gameday graphics and high-definition video that will let users of the new iPad get the most out of that retina display.
At Bat is available as a single app for phones and tablets on the iOS and Android platforms, and for the first time, it offers fans several subscription options. It is also available for Amazon's Kindle Fire, and it supports Blackberry phones with 5.0, 6.0 and 7.0 operating systems.
